BARB-WlRE-FENCE MACHINE.

SPECIFICATION forming part of Letters Patent No. 253,314, dated May 23, 1882. Application filed March 30. 1882. (No model.)

To all whom it may concern Be it known that I,FLY1) EJPA'I'TERSON, of Chicago, Cook county, State of Illinois, have invented certain new and useful Improvements in Barb-\Vire-Fence Machines, of which the following is a specification.

This invention relates to machines for the manufacture of barb-wire fencing. I have endeavored in devising it to produce a simple,

to strong, and inexpensive machine, capable of making fencing of one or more varieties, armed with either two or four point barbs.

The nature of the invention is fully set forth in the following description and claims, and

1 need not be here preliminarily cited.

In the accompanying drawings, forming a part-of this description, Figure l is a plan of my improved machine. Fig. 2 is a longitudinal vertical section upon the line .10 a: of Fig. 1.

2'0 Figs. 3, 4, and 5' are all transverse vertical sections upon the lines 3 y, z z, and w to, respectively. Fig. 6 is a detail elevation of the barb-feeding rolls. Figs. 7, S, and 9 are enlarged detail views of the gears whereby the 2 barb feed-rolls and the main wire feed wheel are actuated. Fig. is'a detail elevation of thespindle holding andadjusting device, and Fig. 11 a central section of the same at right angles to Fig. 10. Fig. 12 is a horizontal see 0 tion of one of the knife-heads on line a o of Fig. 5, enlarged.

The wire passes into the machine from two coils supported upon the arm A, bolted to the main frame A, entering first the grooves m in a non-rotating spindle, B, the projecting end whereof rests in a notch in the upright M, adjustably secured to a riser, B, or bearing upon the bed-frame, While its major portion is supported in a sleeve, 13". This sleevc,which car- 0 ries upon its forward end the coiling-head B is rotated first in one and then in the other direction by the lever B ,pivoted to the frame at b, and having at one end a segment which gears with the pinion B upon the sleeve. The

5 lever is oscillated upon its pivot by the cam 13 upon the shaft B said shaft being driven by the gearing B B shaft B and belt-pulley B In'order that the lever B may be given a greater or less throw, the wrist-pin b which enters the grooves ofthe cam, is adjustably held in a slot, D in the end of the lever, the amount of the coilgi'ven the barb being thus regulated. The sleeve and coilerhead are advanced at proper intervals to seize and coil the barb by the shifting lever O, pivoted to the machine at c, and operated at the required times by the cam-wheel 0 upon the same shaft B, the end of said shifting lever resting upon the rim of said wheel, with depending pins c at either side thereof, so that the lateral curves 0 in the rim move the lever from side to side, and the lever is at all times under the control of the wheel. The latter is so fashioned that it will retain the coiler in the advanced position the necessary length of time to complete the barb-coiling and retain it in the retreat position long enough for the barb to be severed and the fence-wires to be fed forward a barb-space. The attachment of the shifter to the sleeve is by means of the two-part collar 0 screwed to the sleeve, having a circumferential groove, in which is fitted loosely a. collar, 0 which is held in the yoke by the set-screws 0 The barb-wires are fed in during the advance feed of the fencewires by the feed-rolls D D at either side. The shafts of these rolls carry each a pinion, d, whereby one of each set gives motion to its mate, andthe ones so imparting motion are also provided with mi'ter-pinions d, which mesh with other Initers, d upon the horizontal shaft D running across the machine and receivingmotion intermittently from the shaft B by means of the gear D upon the shaft D and the mutilated gear D upon' shaft B The meshing parts of these gears are peculiar, consisting of broad and narrow teeth arranged in pairs, as shown, the broad teeth being designed to take the shock and wear of starting -the alternately stationary part. If 0 teeth of ordinary width were used, they would be liable to be broken by the sudden starting of the parts. Said gears are also provided with means for locking the barb-feed during the intervals between the feed, consisting of 5 the projections (1 standing out from the periphery of wheel D and the rim of the wheel D Said projections 61 are provided each with surfaces beveled in opposite directions at an angle to the plane in which the wheel moves. 10o

Between these projections is an unoccupied space, at, The wheel D has a projecting beveled rim, d continuous around the wheel, except at the point opposite the teeth borne by said wheel. The result brought about by this construction is that as soon as the wheel D has carried the gear D the distance prescribed for each actuation of the latter the beveled rim d enters the space cl and rotates therein in constant contact with-the converging surfaces of two adjacent projections, d By reason of this contact of the rim and projections the barb feed-rolls can neither feed nor with-. draw the wire until the wheel D has brought its teeth again into mesh with those upon the wheel D Between the feed rolls and the point where the barb-wire is severed the wire is caused to pass through tubes 8 for its better guidance.

The knives E for cutting off the barb-wires are mounted in pairs upon the heads E, which slide in the guides E These heads are recip- I'ocated at proper times for the performance of their functions by the cams E upon the shaft B and the pivoted levers E connecting the heads to the cams. The cams E are alike, except that they are reversed to operate the levers in opposite directions. The wrist-pins 0, whereby the levers are joined to the heads, may be flattened slightly, as shown by the upper one, to prevent their turning, and thus become loosened from the head.

6 are removable brass gibs, adjustable through the medium of the screws 0 whereby the guide or holders E are saved from wear and the wearing-surface is rendered easily renewable.

The fence-wires pass from the barb-applying devices around a feed-wheel, F, and from thence back under the machine to the twister, thejournal whereof is shown at G. The wheel F receives intermittent motion from the combined gear and Ice: wheels F F the former upon the same shaft with the feed-wheel and the latter upon the shaft B Said wheels F and F are, except in size, identical with the wheels D? and D respectively, and perform for the feed-wheel F the same service which is performed for the barb feed-rolls by said wheels D and D The twister is actuated from the shaft 13 the gears G, G and G Said shaft is supported upon the frame of the machine by arms H, as shown.

The spindle B is oval in cross-section, and the adjusting-holder M is constructed to fit the flat sides thereof, so that the spindle cannot rotate. To permit changes in the position of the spindle, whereby the wires may be fed in a different relative position from that shown, the holder M may be tilted from the vertical toward either side, and the set-screw n, whereby it is secured, and the slot 0, through which the screw passes, are provided to allowthis adjustment- This holder also prevents the rotation of the spindle through friction with the sleeve, and does not interfere with the reciprocating movement given to the coiling devices.

I do not herein claim, independent of its connection with other parts of the machine, the device shown for converting continuous into intermittent rotary motion, consisting of the combination of a continnously-rotating mutilated bevel-gear having a broken rim with a bevel-gear having circular locking-depressions in its periphery adapted to engage with the circular part of said broken rim, as I intend to make the same the subjectmatter ot' a sepa rate application for a patent.

I claim- 1. In a barb-fence machine, the grooved spindle B, in combination with theadjustableholder M and the sleeve, substantially as specified.

2. The grooved spindle and its adjustable holder, in combination with the sleeve encircling the spindle and the coiling-head carried by the sleeve, substantially as specified.

3. The combination, with the continuouslyrotating mutilated bevel-gear D having broken rim d of theintermittently-rotatingbevel gear D provided with circular depressionsin its periphery, adapted to engage with the circular part of the rim (i for the purpose of intermittentlylocking the gear D thefeed-rolls, and mechanism for driving the same from the intermittently-rotating and locked gear D substantially as specified.
